Abstract

The simple spin casting technique has been successfully used for producing mesoporous thin films on glass substrate. The films are found to be homogeneous and continuous in a large size scale, however, the mesostructural phase of the film has been controlled systematically among amorphous (A), one-dimensional hexagonal (1-dH), cubic (C) and Lamellae (L) by increasing surfactant to TEOS concentration ratio in the casting solution. The 1-dH as well as cubic structure is thermally stable after the calcination so that a mesoporous thin film is obtained by surfactant removal. The solution additives of 1-propanol and 2-butanol might play a roll in the direct formation of the primitive cubic phase in the film form which has never been obtained.
